LABELNG TJIGHENE.

To all w from it may concern.'

.Be it known that l, EDwiN DONALDSON.) a citizen of the United States, and a resident of Brooklyn. Kings County, and State of New York, have invented certain new and useful Improvements in Labeling Machines, of which the following is a specilication.r ref` erence being had to the accompanying drawings, forming a part thereof.

rllhis invention relates to apparatus for ap plying labels or wrappers to articles such as cans or other containers.

The general objects of the invention are to provide an automatic machine which will require practically no other attention than the supplying of labels and articles to be labeled and which will operate to rapidly. accurately and securely apply the labels or wrappers to the cans or other articles.

A special object of the invention is to insure the proper fastening of the label with but a relatively small amount of glue or other adhesive. ln this connection, it is one or' the aims of the invention to improve the adhesive applying mechanism so as to prevent gumming the machine and to enable the removal of practically the entire adhesive applying mechanism from the machine as a unit.

Uther objects and features of the invention relate to the mechanism for wrapping the labels about the articles, the means for transferring the labels from the hopper to the wrapping devices and to special mechanism for stopping the operation of the machine in case the articles being` labeled should become exhausted.

All of the foregoing and other features of the invention will appear as the specification proceeds.

In the accompanying drawings l have disclosed the invention as embodied in machine for labeling relatively small cylindrical cans or containers, but would have it understood that this is only one of the uses of the invention and that changes and modi i'ications may be made without` departure from the true scope and spirit of the invention.

ln the drawings referred to Figure 1 is a side elevation and part sectional view of the complete machine.

Figure 2 is an end view of the same.

To facilitate an understanding of the in- Cri vention, l will first briefly describe the operation of the machine shown and for that purpose will refer to the diagrammatic iews, Figures 230 to 32 respectively.

ln Figures 20, 21 and 22 l have illustrated how first the glue or other adhesive is applied to the labels. 1n these views 40 desig` nates a stack of labels supported in a suitable hopper with the bottom label exposed. 41 designates a glue-pot in which operate glue rolls 42, 43 and 44 spaced to be engaged by the doctor or transfer rolls 45, 46 and 47 and which latter rolls are carried by swing ing arms 48 operating about the center 49. 50 and 51 designate adhesive applying and label. transferring arms swinging about the center 56 and designed to contact the lowermost label at points adjacent the ends thereof. 53 designates an adhesive applying arm operating about the center 54 and positioned to engage the intermediate portion of the label at a point between the two transfer arms 50, 51.

The transfer rolls 45, 46, and 47 are positioned to register with the glue rolls 42, 43 and 44 respectively and rolls 45 and 47 are positioned to register with transfer arms 50 and 51 while the intermediate roll 46 is positioned to register with the single adhesive applying arm 53.

.ln Figure 2O the doctor rolls are indicated as having engaged the glue rolls and the single adhesive applying arm 513 is indicated as on. its upward stroke and as about to engage the upwardly swinging doctor roll 46. ln Figure 21 the adhesive applying arm has engaged and applied a transverse strip of adhesive to the bottom label and the doctor rolls 45 and 47 are engaging the arms 50, 51 of the transfer device.

ln Figure 22 the arm 5B has left the label, the spring hold-back linge rs 55 carried thereby preventing the label Yfrom following said arm, the transfer arms 50, 51 are swinging towards the stack oflabels and the doctor rolls are swinging down to again engage the glue rolls.

ln Figure 23 the transfer arms are shown engaged with the bottom label to apply transverse strips of adhesive to the end portions of the label. rlhis view also shows how the transfer arms are carried by a shaft having a half-round portion 57 on the end thereof rotating in a part-round pocketor depression 5S at the end of a track and a flat side 63. This view also shows how the transfer arms are operated by a sliding rack 60 engaging a gear 61 on the shaft 56.

As the swinging arm 62 which operates the rack moves to lthe right, the transfer shaft 56 is rotated, causing the transfer arms to swing away from the stack of labels and, by reason of the adhesive, to carry the.

bottom label with them. The transfer shaft continues to rotate until a position is reached such as indicated in Figure 24 where the half-round portion 57 of the shaft rotates out of the pocket 58 and the fiat side 63 of such half-round portion registers with track 59. whereupon the shaft is free to slide over said track. rlhis released condition is indicated in Figure 24, which also shows the label 64 adhering to the t ansfer arms.

As the lever 62 swings further to the right, the rack, carrying with it the transfer shaft, is shifted to the position indicated in Figure 25 where the label is then supported in position to be operated on by the wrapping devices.

Figure 26 is a view of the label as supported in this last position, this view being taken looking in the direction of the ,arrow 26 in Figure ln this view -two of thearticles which are being labeled are indicated at 65 in the lower end of the feed chute 66, the lower article being held by a gate 67 which is connected with a second or cut-off gate 68 by a walking beam 69.

This walking beam is oscillated as indicated in Figure 27 to lift the hold-back gate 67 and at the same time to drop down the cut-off gate 68 to stop the second article. The released article falls down onto the label which is then supported above two spaced label applying members or rolls 70, 71.

Figure 28 shows how the released article is then forced down against the label between the two label applying rolls by means of the two plungers 727 723, which hold the article, with the label wrapped thereabout against the support 74 while rolls fasten down the ends of the label.

ln Figure 29, the first label applying roll is indicated as having been rocked about the ri glit-hand side of the supported article to wrap the first end portion of the label about the article.

Figure 30 illustrates how at the end of this label applying movement, tl roll 7() is tripped from contact with the label so that` on its return stroke it will not Contact with the label.

After the first label applying roll has done its work, as shown in Figure 31, the second roll 71 is advanced about the supported 1" article to wrap the label thcreabout and to seal the other end ofl the label down over the first secured end.

While the second label applying roll is in its upper position, as shown in Figure 32, the supporting head 74 on which the article has rested during` these last mentioned more ments, is retracted and is tilted by reason of. its engagement with a stop 75 so as to dis charge the wrapped article onto a discharge chute 76 which delivers the same onto a carrying-olf belt or conveyor 7 7.

From this it will be seen that relatively narrow transverse strips of. adhesi ve are first applied to the intermediate and end portions reise@ and that the label is applied to y irst engagino' the intermediate i. dhesive therewith7 then bringing one en of the label into adhering eneinent with the article and then tastenthe otheel end ot the label down over the 1 sseured end thereof.

"iff up now the detailed construction the inaehine illustrated, it will be seen in Figures l and 5 that the label hopper is made up ot a series oit lingers disposed to torni an open-ended box or compartment tor holding a stack ot labels and having in urned lower ends at 8l to support the stael an d to releasably hold the bottoni label. the labels are removed from the bot toon the stack is loreed downward by a fol lower 89 which rests on the top of the staelr and which holds the stack down against the upward thrust ot the adhesive applying arnis h v springl plate carried by the post 84: oi the follower and having a sliding, Yfrietional, gripping engagement over the relatively stationary post 85. rThe engagement ot this spring` hold-down over the post 85 is suoli as to perinit the plate to readily slide downwardli7 over the post, but to cause it to hind against the post when an upward thrust is exerted on the follower. The follower thus drops down with the stack and :it each new adjustment yieldingly opposes the upward thrust of the adhesive applying levers against the bottom ot the stack.

The glue-pot al, as shown particularly in liigjuros 8 and l5 is in the form of a pan haring; rils or flanges 8G slidingly litting in `nuide-wavs provided therefor in the suppor traine 87 (Fig. l.) and the shaft 88 which ear-ries the glue rolls 42. il?) and. t is journaled direetly therein so that said rolls are reniovableas a unit with the flue-pot.

fi (l is operated by a linl; 161 connected with a swir'z'ing lever carrying a cam roll 163 (Fig. 2) in engagement with a cam 164i.

rllhe cams last referred to and the connections `thereliroin are so designed as to effect the sequence ot action previously described, that is to cause the lirst roll to advance and wrap one end ot the label about the can and to then trip and retract, the other roll then advancing to wrap the other end or' the label about the can and sec-ure the saine over the first secured end of the label.

The plunge-rs 72, 73 which torce the article and hold it down against the label between the label applying rolls and onto the support 711 (Figures 3 and L1), are carried by a slide 165 working in a guide-way 166, said slide carrying an outstanding pin or stud 167 engaged by the forked end ot a lever 168 on roel: sha-lt 169, which carries a rock arm 170a (Figure 1) operated by a link 170 which is connected at its lower end with a lever 171 pivoted at 172 and larrying a cam roll 173 engaged with a cam 174i on the ram shaft 123. The plungers 72, 73 are shown in Figure 4- as set in the opposite edge portions of slide 165 by having head portions 175 at their upper ends en'- gaged in corresponding seats in the face of the slide and one of t-hese plungers, namely 73, is shown as having a pivotal movement about its center ot support at 175 and as being yieldingly pressed toward the adjacent end oi the can or other article by a spring 176. This permits the plunger mechanism to accommodate itself to slight variations which may occur in the size o1 the cans and also causes the plunger to fit snugly over a bea-d 177 which may ordinarily be provided on the end of the can. Also, this plunger 73 is shown as undercut as indicated at 178 to receive this bead. Both the plungers 72 and 73 are shown as recessed so as to lit over the corners or end et gos oit the article so as to exert a centering etlect on Vthe article as well as to engage over the top ol the same lor the purpose of exerting the downward thrust thereon.

i lost `motion connection is provided in the present illustration 'for effecting the proper sequenze ot action between the gate mechanism and t-he plunger mechanism, said connection being shown as a pair of spaced stops 179, 180 on the baclr of the slide 16:3 (Figure 3) and arranged in the retraction et the slide to engage an eXtension 181 on the forward end of the walki ing beam 69. This walking beam is shown as coupled to the two gates 67, 68 by means ol the slots 182, 183 provided at opposite sides ot the pivotal center 184 thereof and receiving the pins 185 and 186 on the gates 67 and 68 respectively,

1n the position illustrated in Figure 3 where the plungers have descended and forced the can and with it the label between the two spaced label applying rollers, the upper stop 180 has engaged the forward end ot the walking beam and rocked the same downwardly so as to lower the gate 67 and raise the gate The lower gate is then in holding engagement with the last article in the chute. @n the upward movement of the slide 165 and approximately at a time when the plungers have cleared the passage i'or the articles, the stop 179 engages the end 181 ol the walking beam and rocks the same upwardly so as tolift the lower gate 67 to thereby release the last article, and lower the upper gate so as to catch the neXt to the last article. This upper or cut-off gate 68 is preferably provided with a butler to cushion the impact of the row of articles in the chute` said butler being shown as a plate 187 yieldingly supported on the upper tace ot the cut-oil gate by a spring 188. The two gates 67 and 68 are shown as guided respectively in suitable slots or guide-ways 189, 190 provided in the upper trame work ot the machine.

ritter the label or wrapper has been coinpletely applied to the article and firmly secured thereto, the article is discharged from the wrapping mechanism, .in the macnine illustrated, by tilting` the article support 74 in the manner indicated in Figure 32. Referring to Figure 3 it will be seen that the article support 741 is in the nature ot a head pivoted at 191 to one side of the center o1 a spring` supported post 192, said pivot-ed head having a bearing on the relatively lined stop or shoulder and being held normally engaged with said shoulder by the spring 193. lt will be clear 'from the views referred to that when the post or plunger 192 is in its upper position, the pivoted head 7151- will 'Form a firm support tor the article and that when the post 192 is retracted or depressed the pivoted head will slide over the stop 75 as a ulcruin and will be tilted in such a way as to discharge the wrapped article therefrom and toward the left in Figure 3. The post 192 is operated to thus discharge the article by means ot' a suitable cam 1911; engaged by the cam roll 195 (Figure 1) and the parts are preferably so timed that this discharging` movement will take place at the time that the second label applying roll 71 is inv upraised condition, as illustrated in Figure 32 and theretore out of the way of the discharging movement ot the article.

The wrapped or labeled articles may be carried oit and away trom the machine by means o't a suitable belt conveyor such as illustrated at 77 in Figures 2 and 32, said conveyor receiving the articles from the discharge chute 76 which, at its lower end, is provided with a suitable guide 196 for dropping the articles into position on the conveyor.

In addition to the features above disclosed, my invention involves also the provision'of suitable stop mechanism for interrupting the operation of the machine when there are no articles present to he labeled. This mechanism is illustrated particularly in Figureswl, 2, 18 and 19 and comprises, generally speaking, a clutch on the drive shaft 197 and which is controlled by the presence or absence of articles in the feed chute 66. The drive shaft 19T is shown having a bevel gear connection 198 at ils inner end with the cam shaft 125i and as provided at its outer end. with a drive pulley 199. This drive pulley is coupledl to the shaft by means of a pin 200 arranged to take into a slot or slots 201 in the face of the pulley and sliding in. a groove 202 in a collar 208 which is fast on the shaft. This clutch pin is normally forced outward to engage in the pulley slot by a spring 204i and the operation of this pin is controlled by a plunger 205 having a shoe 206 at .its lower end received in an annular groove 0T in the collar 203, said slice hzwinga portion of reduced width at its forward edge at 266 to act as a wedge for the purpose of engaging in a transverse or inclined slot 20S) in the outer face of the clutch pin. Hhe clutch controlling plunger 205, when the machine is in operation, is held supported in an elevated position where the shoe at the lower end thereof is clear of the clutch pin,v the means illustrated for this purpose comprising a latch 210 arranged to engage a pin 211 on the plunger, said latch. being pivoted at 212 and normally held engaged with said pin by a spring 213.

Provision is made in the machine illustrated for manually tri pping the latch, the same comprising a handle 214r pivoted on the frame of the machine at 215 and carrying a pin 216 working in an inclined cani slot 217 in the upper end of a trip lever 218 which is pivoted at 219 and engages at its lower end with the upper extended end 220 of the latch member.

lt will be seen from Figures 16 and l) that when the handle 214 is dcpressefl. the pin 216 will, through the cam connection illustrated, rock trip lever 21S and cause said lever to rock the upper end of the latch lever 210 in such a way as to free the hook on the lower end thereof from engagcniientV with the pin on the clutch plunger. The plunger' when thus released is thrown downward by its own weight and also by the action of a spring 221 in the illustration, causing the shoe on the lower end thereto to drop in the annular groove in the collar, in which position the reduced forward end. of the shoe enters the slot in the face of the clutch pin and withdraws the same free of the seat in the driving pulley. This stops the machine ]Viractically instantaneously and prevents the adhesive supplying parts from gumming up any of the other parts of the machine.

The machine may again be started after articles have been supplied to the feed chute by simply lifting up the control. lever 214i which causes the pin 216, operating in a slot 222 in the upper end. of the plunger to pick up the plunger and lift it to a position where the latch 21() will again snap into holding` engagement with the pin 211.

Provision is made for automatically stopping the machine, in the ease illustrated, by a feelcr or detector disposed in the path of the articles being fed to the wrapping mechanism and shown as a spring arm supported on an insulating block 224 and having` an active portion disposed in the feed chute and of a length sufficient to be contacted by the lasttwo articles inthe chute, said spring arm having an introverted `portion 225 overstanding a contact member 226 on the insulating support 224'. The relatively insulated contacts 225 and 226 are connected in circuit by means of wires 22T, with a control magnet 229 shown in the form of a solenoid having a core 23() connected with a pivoted lever 231 which in turn is connected with a link 232 connected with the sustaining latch 210. lnter'posed in the circuit connections for this magnet .is a suitable battery or other source of electric current and there will ordinarily be included in this circuit a suitable control switch. and preferably a suitable ani'iunciator in the nature of a buzzer or the lille, as shown at 234, to give notice to an operator, who may thus be enabled to take care of several machines.

With the construction just described, the contacts will remain out of engagement so long as there are articles in the feed chute but as soon as the last article is dropped down to the wraplriing mechanism, the contact spring, being no longer restrained, will engage the rel atively stationary contact 226, an d establish a circuitv through the trip magnet which, operating through the connections described, will. trip the lat-ch and release the clutch plunger which will voperate in the saine way as before described to stop the machine. ln stopping the machine the parts will ordinarily come to rest on the eompletion of the application of the label to the last article in the machine and before the adhesive applying arms have operated to taire another charge of adhesive. ln this way gumming of the machine is avoided and at the same time the operation on the last article in the machine is completed.

The machine operates rapidly and effectively to firmly secure the labels or wrappers. By suitably modifying the parts, ar
